l SPECIFICATION forming part of Letters Patent No. 628,385, dated July 4, 1899.

Application led August 9, 1898. Serial No. 688,165. (No model.)

To @ZZ whom, it may concern:

Beit known that I, CHARLESA. BELKNAP, a citizen of the United States, residing at New York, borough of Brooklyn, State of New 5 York, have invented certain new and useful Improvements in Machines for Addressing Envelops or Wrappers, of which the following is a specification.

This invention relates to that class of maxo chines foraddressing wrappers, euve1ops,&c., in which a perforated stencil-card is used; and the. object of the present invention is to render this class of machines more compact and light, so that they 'can be readily transported by hand from place' to place.

The invention consists of a suitable frame, a movable stencil-carrier mounted on said frame and provided with ways along which` the perforated stencil-cards are caused to travel, a supporting plate or bed upon which the articles to be addressed are placed, a laterally-movable impression-roll, means for moving said roll, an ink-reservoir in which an hiking-roller turns, means for intermittently turning said roll, a transfer-roll adapted to transfer the ink from 'the inking-roll to the y impression-roll, and means for oscillating said transfer-roll, as will be hereinafter described and then particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved machine for addressing wrappers, envelops, 85o. Fig. 2 is a plan View of the same. Fig. 3 is avertical longitudinal section on the line 3 3 of Fig. 2, parts being in elevation. Figs. 4 and 5 are transverse sections on lineseiliand 5 5, respectively, Fig. l. Fig. 6 is an enlarged detail View, in longitudinal section, through the stencil-carrier, the inking mechanism, and adjacent parts, parts broken away. Fig. 7 is a broken detail section of the lower portion of the collecting-box for the perforated stencil-cards. Figs. Sand 9 are detail end views of the inking mechanism, looking toward the opposite side of Fig. 4. Figs. l0, ll, 12, and 13, inclusive, are detail views, partly in side elevation and partly in section, of the pusher mechanism.

Similar letters indicate corresponding parts. A indicates the frame of the machine,which at one end is provided with an elevated impression bed or table A',while at the other end of the frame, in suitable bearings tt, is journaled the driving-shaft B, on which is fixed, at about the mid-length of the machine, a largecylinder-cam C, which is provided with camgrooves O C2, respectively, while between the cylinder-cam C and the beltpulley B is placed a smaller cylinder-cam D, provided with a 6o cam-groove d. These cams elfectu ate the operation of all of the working parts of the ma-v chine through the medium of certain instrumentalities now to be described.

At the upper part of the frame Aare located longitudinal guide-rails E, upon which are guided the transverse slides F F', which are provided with pins ff', respectively, upon which are placed suitable antifriction-rollers and that are received in the cam-grooves O' O2, 7o respectively. The slide Fis provided with a bifurcated bracket or fork F2, which engages a stud g on one end of a reciprocating rack-bar G, that is suitably guided along one side of the stencil-carrierH, which is pivoted at h to the bracket H of the frame A. The stencil-carrier H extends approximately from end to end ofthe machine, and its rearwardlyprojecting end is connected bytoggle-links I with the frame A of the machine, so that 8o through the medium of the slide J, which has a pin-and-slot connection j with the togglejoint and the pin y", which takes into the camgroove d of the cam D, the said stencil-carrier is oscillated at the proper moment of time. The companion slide F' of the slide F is provided with upwardly-extending forks or bifurcated brackets F3, which engage with studs k on the rear ends of reciprocating bars K, that are suitably guided on the sten cil-carrier 9o and are connected by a shaftKz, journaled therein, and which passes through slots 7L' in the sides of the stencil-carrier. The shaft K2 carries at one end a gear-wheel K', which meshes with the teeth of rack-bar G, and also carries a suitable impression-roll L, which moves between the sides of the stencil-carrier and is adapted to travel over the surface of the impression bed or table A when the stencil-carrier isrpressed down upon the same.

Upon the rear part of the stencil-carrier H the receiving-box M for `the perforated sten- IOO ' myself to this arrangement, inasmuch as iustead of moving'with the stencil-carrier it is evident that the said receiving-box can be supported in stationary position similarly to the collecting-box N, which is supported at the front end of the machine by means of a suitable arm N',extending upwardly from the frame A. v This. alternative arrangement of Ithe boxMis evident withoutanydetailed illustration.

Extending along the sides of the stencil-carrier from a point below the receiving-box M are ways h2, along which the perforated stencil-cards m are adapted to be moved until the forward card arrivesbetween theim pressionbed A and the collecting-box N. rlhe cards fm, being of the usual formation-that is to say, with an exterior frame of pasteboard ,onto which is pasted a sheet of parchment-are Aadapted to be pushed along the ways h2 by means of suitable pusher mechanism, the pusher of which engages with the inner edge of the exterior frame, thereby avoidinginjury to the outer edge of the same. The pusher mechanism consists of a transverse slide-plate O, which extends from one side toward the slot connection p is a cheek-plate P, which is adjustable upon the shoe so as to I imit the stroke of the push-pawl, said cheek-plate being provided with a transverse slot 2J', Which receives a stud or pin p2, projecting inwardly from the rear end of the reciprocating rackbar G. The object of this pin-and-slot connection 19'192 is to cause the push-slide to be moved together with the rack-bar G, for if this connection were not provided it will be seen that .the inclined arrangement of the Ways 724 for the push-slide would prevent the working of the same. The object of this inclination of the ways h4 is to prevent the interference of the cheek-plate P with the longitudinally-reciprocating bars K of the impression-roller.

A projection p3 on theV cheek-plate P is guided in a longitudinal groove p4 in the bar K, so as to hold the saine down duringits reciprocation and to prevent the release of studs 7e from the forks F3.

Supported on the stencil-carrier between the receiving and collecting boxesis thereservoir Q in suitable bearings, of which an inking-roll Q is adapted to turn, said inkingroll being provided with an exposed portion, over which the ink is kept equally distributed by means of suitable doctor-s q q.- Referring particularly to Figs, 8 and 9 in connection 4With Figs. 3 and 6 it will be seen that at one end of the inking-roll Q' is arranged a ratchetwheel R, that turns with the roll and the teeth of which are adapted to be engaged by a spring-actuated .paWl 0", that is pivoted to fastening screws or rivets S' to one of the reciprocating bars K of impression-roll L. The inclined surface of the cam S works against an antifriction-roller t, Which is jou rnaled on a pin t', projecting from' the oscillating arm Pivoted at u to the stencil-carrier Hare arms U, in the outer ends of which the transfer-roll V is journaled, while supported by a side extension W of one of the arms Uis a projecting tappet-arm W', which carries at its free end au antifriction-roller W2, adapted to be 'engaged by meansof an angular cam X, which is firmly fastened to one of the longitudinally-reciprocating bars K in such position that as the impression-roll L travels forward the said cam X causes the tran-sferroll to be pressed up in contact with the inkingroll Q', so as to receive the ink While the impression is being made by the impressionroll.

The operation of the machineis as. follows: The appropriate stencil-cards m, according to the addresses which are to be printed, are placed .in the receiving-box M. The other parts of the apparatus being in proper'ordcr, the mechanism is set in motion. Awrapper or envelop is now inserted between the stencil-carrier and the impression-bed A' and IOO placed on thelatter after the forward stencilcard has been pushed forward' and while the stencil-carrier H is raised.y Durin-g the low; ering of the stencil-carrier through the medium of its oscillating cam D theI rack-bar G is moved forward, at the same time causing the push-pawl O' to push forward the lower card located in the receiving-box M or atthe rear end of the Ways in which the stencilcards are guided. The cam-grooves C' C2 of the cam C are so formed as that at the proper time-that is to say, at the moment of dwell of the stencil-carrier upon the impression-bed A --the reciprocating bars K through themediu m of the slide F are pushed forward, thereby causing the impression-roll L to travel over the stencil-card along the same and to press the ink through the perforations in the same, thus imprinting the address upon the article placed upon the impression-bed A. At the i moment that the impression-roll Lis traveling i forward over the impression-bedA the transfer-roll Vis being moved up in contact with the surface of the inking-roll so as to receive the ink. Just before the stencil-carrier H rises the reciprocating bars K, which support the im- Then the stencil-carrier H is rising, the rack- IZO bar G is being moved back, thereby turning the impression-roll in contact with the transfer-roll, so as to transfer lthe ink onto the impression-roll.

The play of the stencil-carrier is limited between the impression-bed A and the collecting-box N, and when the stencil-carrier arrives at the limit of its upward movement the stencil-card which has been used is snapped in between the down wardly-projecting sprin gcatches N?, arranged on the said collectingbox, (see Figs. 6 and 7,) so that the said catches take up each stencil-card as the stencil-carrier is moved up against the said collecting-box. By the above-described construction machines for addressing wrappers, envelops,&c. are rendered more com pact-,and by the employment of the cams the parts are so properly timed in their movements as that the reliable working of the machine is produced. After the cards have all been used up they will have been transferred to the collecting-box, from which they are then removed, a new supply of cards being then placed in the receiving-box.

Itis evident that various changes in the construction and arrangement of the parts will suggest themselves to skilled mechanics, and I do not therefore limit myself to the construction shown and described, as any machine which willV accomplish the Work done by the machine in a similar manner is wit-hin the province of my invention.

I-Iaving thus described my invention, I claim as new'and desire to secure by Letters Patent- 1. In a machine'for addressing envelops or wrappers, the combination, with an impression bed or table, of a stencil-carrier movable relatively to the same, and provided with ways along which the stencil-cards are adapted to be fed, and means coperating with the stencil cards for` printing upon the article placed upon the impression bed or table, su bstantially as set forth.
